Bruce,

only short answer. We all have experience with our particular cave  
system or areas. They are very very different.

Therion was developed for documentation of quite complicated cave  
with many levels overlapping each other. It works in many other cases  
depending on imagination of its user.

The main principle is that the map itself is divided into small  
pieces - scraps. The scraps are absolutely independent from survey  
structure created more or less historically. You may use in one scrap  
data from several surveys made historically in very long interval by  
different surveyors. Only condition is all the data are accessible in  
survey which include the map structure with that particular scrap.

The main rules to create such structure is to divide the system into  
horizontal layers (in case of map) which the atlas will be able to  
recognize and shows in enough simple way. There one may see the  
importance of idea of scraps -you may reorganize your structure  
anytime in the future.

The main problem is organize the maps and submaps. The structure of  
survey data itself is existing more or less automatically.

I hope MartinB or Stacho may add more.

Martin
